Shamanism is an ancient energy practice that began many centuries ago. In most cultural traditions, shamans transcended the order of the material world, healed the members of their community and stayed outside the power struggle, serving as advisors to the rulers; However, this has not always been the case: the Olmecs and Teotihuacans had governments led by shamans. There are many mythological and cultural coincidences of the Siberian, Eskimo, Aleut, Tungus and Inuit shamans with those of the Olmec and Teotihuacan shamans; as can be seen in the Teotihuacan murals of Tetitla, in which shamanistic practices and the use of Power Plants are observed. This is more representative of the Day of the Dead festival.
